Abstract
The 29 plant species in the Kadsura genus of the Schisandraceae family are mainly distributed in eastern and southeas-tern Asia. Ten species of plants in this genus are distributed in China, some of which are folk medicinal plants with activating blood circulation, relieving pain, dispelling wind, and dehumidifying effects. Their main constituents are lignans and triterpenes. The current pharmacology and clinical studies have shown that their extracts and constituents have anti-rheumatoid arthritis, liver protection, antioxidation, anti-inflammatory, and other biological activities. The rheumatologic and liver diseases can also be treated with the plants in the clinic. The new chemical constituents reported in the last decade(2012 to date) from the plants of Kadsura genus in China, as well as their pharmacological effects and clinical applications in recent years were reviewed, so as to provide a theoretical basis for further research on the genus.

Abstract
Objective: To analyze the epidemiological characteristics and related factors of hepatitis C in Beijing City from 2004 to 2021. Methods: Descriptive epidemiological method and Joinpoint regression were used to analyze the trend and other epidemiological characteristics of hepatitis C in Beijing City from 2004 to 2021 in National Notifiable Disease Reporting System. According to a 1∶1 matched case-control study design, logistic regression was used to investigate the risk factors of hepatitis C infection in 2021. Results: From 2004 to 2021, the reported incidence of hepatitis C in Beijing City ranged from 2.37/100 000 to 10.46/100 000. The reported cases were mainly aged 30-60 years, and most of them were chronic. The reported incidence of hepatitis C showed an initial increase from 2004 to 2006 (APC=45.37%, 95%CI:-1.56%-114.69%), and declined after 2006 (APC=-9.21%, 95%CI:-10.70%-7.70%). Logistic analysis showed that history of surgery (OR=1.84, 95%CI: 1.08-3.14) and previous blood transfusion (OR=34.22, 95%CI: 8.05-145.41) were risk factors for hepatitis C infection. Conclusion: The reported incidence of hepatitis C in Beijing City increases first and decreases later. It currently remains at a low level. The risk factors of infection are surgery and blood transfusion history. Safe blood supply and preventing iatrogenic transmission should be focused on the prevention of hepatitis C transmission.

Abstract
Objective: To explore the clinical application and efficacy of lateral upper arm free flap (LUAFF) for one-stage repairing of soft tissue defect after oral cancer surgery. Methods: This article was a retrospective analysis of clinical data of 46 patients receiving treatment of one-stage repairing of soft tissue defect with LUAFF after oral cancer surgery in Hunan Cancer Hospital, from June 2019 to June 2021. Among these cases, 40 were males, and 6 were females. The patients' ages were from 23 to 64 years old. The clinical data of patients were reviewed and outcomes were evaluated. SPSS 23.0 software was used for statistical analysis. Results: In the LUAFF of 46 patients, flap area ranged from 5.0 cm×3.5 cm to 15.0 cm×7.0 cm; the mean pedicle length was 8.15±1.42 cm; the mean artery diameter was 1.20±0.41 mm (range, 1.5 to 2.5 mm); the mean diameter of the largest veins was 2.15±0.52 mm; and the median number of perforators was 2.6 (range, 1 to 4). All donor sites were closed primarily. Two cases had arterial anastomosis thrombosis, but their flaps were successfully saved with urgent re-anastomosis of the vessels. The overall flap survival rate was 93.5%(43/46), with flap necroses after operation in three cases. No patient received tracheotomy. The average hospital stay time of patients after operation was 9.4 days. The follow-up time was 6-24 months, elbow and wrist movements on the operative side were normal, and the upper limb muscle strength was not affected. Conclusions: LUAFF is a suitable choice for the repairs of small-moderate tissue defects in oral cancer surgery, with consistent perforators in the flap, simple harvest method, concealed donor-site scar, and high survival rate.

Abstract
Objective: To investigate the type, length, and CG loci of HBV DNA CpG islands in HBsAg positive maternal C genotype and its relationship with intrauterine HBV transmission, so as to provide a new perspective for the study of intrauterine transmission of HBV. Methods: From June 2011 to July 2013, HBsAg-positive mothers and their newborns who delivered in the obstetrics and gynecology department of the Third People's Hospital of Taiyuan were collected. Epidemiological data were collected through face-to-face questionnaires and electronic medical records. Serum HBV markers and serum HBV DNA were detected by electrochemiluminescence and quantitative fluorescence PCR, respectively. Intrauterine transmission of HBV was determined by positive HBsAg and/or HBV DNA in femoral venous blood before injection of HBV vaccine/Hepatitis B immunoglobulin within 24 h of birth. A total of 22 mothers and their newborns with HBV DNA load ≥106 IU/ml in intrauterine transmission were selected as the intrauterine transmission group, and 22 mothers with HBV DNA load ≥106 IU/ml without intrauterine transmission were chosen as the control group by random seed method. The distribution prediction of CpG islands of HBV DNA in 39 mothers with genotype C by HBV DNA sequencing was analyzed. Results: Among 39 mothers with HBV C genotype, 19 were in the intrauterine transmission group, and 20 were in the control group. The HBV DNA of 39 patients with genotype C traditional CpG island Ⅱ and Ⅲ, while the control group had traditional CpG island Ⅰ and novel CpG island Ⅳ and Ⅴ. The length of CpG island Ⅱ and Ⅲ and the number of CG loci of CpG island Ⅱ in the intrauterine transmission group differed from those in the control group (P<0.05). The CpG island Ⅱ length ≥518 bp and the number of CG loci ≥40 in the intrauterine transmission group (11/19) were significantly higher than those in the control group (2/20) (P<0.05). The length of CpG island Ⅱ and the number of CG loci in the X gene promoter region (Xp region) were higher than those in the control group (P<0.05). In the HBV intrauterine transmission group, most of maternal (12/19) HBV DNA CpG island Ⅱ completely covered the Xp region, which was significantly higher than that in the control group (5/20), and the number of HBV DNA Xp region CG loci was higher than that in the control group (P<0.05). Conclusions: The distribution of maternal C genotype HBV DNA CpG islands is related to intrauterine transmission. The length of CpG island Ⅱ and the number of CG sites may increase the risk of intrauterine transmission of HBV.

Abstract
Objective: To explore the effect and mechanism of activation of peripheral blood mononuclear cell (PBMC) Toll-like receptor (TLR3) signaling pathway in recombinant HBsAg (rHBsAg) immune response. Methods: White blood cells were collected from peripheral blood of 13 healthy donors in the preparation of blood products. PBMC was isolated and treated with Poly I:C (Poly I:C group) and PBS (control group) respectively. 48 h later, some cells were collected and the expressions of TLR3 signaling pathway proteins were detected by flow cytometry. After activating (Poly I:C group)/inactivating (control group) TLR3 signaling pathway, rHBsAg was given to both groups for 72 h, and the proportions of DC, T, B cells and their subsets in PBMC were detected by flow cytometry. Paired t-test, paired samples wilcoxon signed-rank test and canonical correlation analyses were used for statistical analysis. Results: The percentage of TLR3 protein-positive cells (19.21%) and protein expression (8 983.95), NF-κB protein expression (26 193.13), the percentage of pNF-κB protein-positive cells (13.73%) and its proportion in NF-κB (16.03%), and the percentage of pIRF3 protein-positive cells (12.64%) and its proportion in IRF3 (21.80%) in Poly I:C group were higher than those in control group (11.54%, 8 086.00, 22 340.66, 8.72%, 9.71%, 9.57%, 19.12%) (P<0.05), and the percentage of TRIF protein-positive cells (89.75%) and protein expression (304 219.54) were higher in Poly I:C group than in the control group (89.64%, 288 149.72) (P>0.05). After PBMC stimulation by rHBsAg, the proportions of mDC (2.90%), pDC (1.80%), B cell (5.31%) and plasma cell (67.71%) in Poly I:C group were significantly higher than those in the control group (1.83%, 0.81%, 4.23%, 58.82%) (P<0.05). Results of canonical correlation analysis showed that the expression of TLR3 protein was positively correlated with the proportions of plasma cells, the expression of pIRF3 protein was positively correlated with the proportions of plasma cells and mDC, and the percentage of pNF-κB protein-positive cells and the percentage of pIRF3 protein-positive cells were positively correlated with the proportion of CD4+T cells. Conclusions: Poly I:C can activate TLR3/TRIF/NF-κB and TLR3/TRIF/IRF3 signaling pathway, promote the function of downstream signaling molecules, and then promote the maturation of DC, induce the immune responses of CD4+T cell, and promote the maturation and activation of B cells and the immune response of rHBsAg.

Abstract
Objective: To investigate the influencing factors of HBV intrauterine transmission and their interaction effects by integrating logistic regression model and Chi-squared automatic interaction detector (CHAID) decision tree model. Methods: A total of 689 pairs of HBsAg-positive mothers and their neonates in the obstetrics department of the Third People's Hospital of Taiyuan from 2007 to 2013 were enrolled, and the basic information of mothers and their neonates were obtained by questionnaire survey and medical record review, such as the general demographic characteristics, gestational week and delivery mode. HBV DNA and HBV serological markers of the mothers and newborns were detected by fluorescence quantitative PCR and electrochemiluminescence immunoassay respectively. The CHAID decision tree model and unconditional logistic regression analysis were used to explore the factors influencing HBV intrauterine transmission in neonates of HBsAg-positive mothers. Results: Among the 689 neonates, the incidence of HBV intrauterine transmission was 11.47% (79/689). After adjusted for confounding factors, the first and second logistic multivariate analysis showed that cesarean delivery was a protective factor for HBV intrauterine transmission (OR=0.25, 95%CI: 0.14-0.43; OR=0.27, 95%CI: 0.15-0.46); both models indicated that maternal HBeAg positivity and HBV DNA load ≥2×105 IU/ml before delivery were risk factors of HBV intrauterine transmission (OR=3.89, 95%CI: 2.32-6.51; OR=3.48, 95%CI: 2.12-5.71), respectively. The CHAID decision tree model screened three significant factors influencing HBV intrauterine transmission, the most significant one was maternal HBeAg status, followed by delivery mode and maternal HBV DNA load. There were interactions between maternal HBeAg status and delivery modes, as well as delivery mode and maternal HBV DNA load before delivery. The rate of HBV intrauterine transmission in newborns of HBeAg-positive mothers by vaginal delivery increased from 19.08% to 29.37%; among HBeAg-positive mothers with HBV DNA ≥2×105 IU/ml, the rate of HBV intrauterine transmission increased to 33.33% in the newborns by vaginal delivery. Conclusions: Maternal HBeAg positivity,maternal HBV DNA ≥2×105 IU/ml and vaginal delivery could be risk factors for HBV intrauterine transmission in newborns. Interaction effects were found between maternal HBeAg positivity and vaginal delivery, as well as vaginal delivery and high maternal HBV DNA load. Logistic regression model and the CHAID decision tree model can be used in conjunction to identify the high-risk populations and develop preventive strategies accurately.

Abstract
Objective: To investigate the effect of exosomes from mild-inflammation- stimulated human dental pulp stem cells (hDPSC) combined with stromal cell-derived factor-1 (SDF-1) on dental pulp regeneration in rats. Methods: Primary hDPSCs were isolated, cultured and then stimulated by using lipopolysaccharide (LPS). The exosomes from the hDPSCs with (L-EXO) or without (N-EXO) LPS were extracted by overspeed differential centrifugation and were identified by transmission electron microscopy and Western blotting. Forty SD rats, aged 6-8 weeks, were equally divided into S group (SDF-1 alone), L+S group (L-EXO combined with SDF-1), N+S group (N-EXO combined with SDF-1) and blank control group (no substance implanted into the root canal) by random number table method. Bilateral mandibular first molars were used as the experimental teeth to establish pulpless root canal models and different contents were implanted into the root canals according to the groups. All rats were over-anesthetized and sacrificed at the 30th day after content implantation. Bilateral mandibular tissues were taken for histological evaluation by means of HE, Masson and immunohistochemical stainings. Results: The HE staining showed new pulp-like tissue in the root canals of all three experimental groups. The amount of new tissues and the number of cells in the tissues were greatest in L+S group and least in S group. Masson staining showed that the mineralized tissue in L+S group was arranged longitudinally along the root canal wall and the collagen fibers were arranged in an orderly fashion, while those in N+S group showed an irregular and disordered distribution. Quantitative analysis of the area of neovascularization in each group showed that the density of vessels in the L+S group [(2.03±0.65)%] was significantly higher than that in the S group [(0.65±0.05)%] and the N+S group [(1.06±0.38)%] respectively (F=5.879, P<0.05). Immunohistochemical staining showed that the expression of CXC chemokine receptor 4 (CXCR4) was significantly lower in S and L+S groups than in N+S group, with a statistically significant difference (F=8.633, P<0.01). Conclusions: Exosomes secreted by hDPSCs combined with SDF-1 might increase the amount of new tissue in the root canal and the density of blood vessels in the tissue. L-EXO showed a stronger effect than N-EXO did. The combination of L-EXO with SDF-1 might result in more regular arrangement of mineralized tissue and collagen fibers in the regenerative tissues.

Abstract
Objective: To analyze the clinical characteristics, treatment and prognosis of Hashimoto's encephalopathy presenting with isolated cerebellar ataxia in children. Methods: A retrospective analysis was performed on the clinical features, laboratory tests, neuroelectrophysiological examination, imaging, treatment and outcomes of 13 patients with Hashimoto's encephalopathy presenting with isolated cerebellar ataxia, who were admitted to the Department of Pediatric Neurology of Guangzhou Women and Children's Medical Center from January 2016 to May 2021. Results: Among the 13 cases, 6 were males and 7 were females. The onset age was 2.6 (2.0,3.3) years, 9 children had precursor infection or vaccination before the first course of disease. All the 13 children had gait abnormalities or unsteady sitting, 10 had intentional tremor, 6 had dysarthria, 3 had body tremor, 2 had nystagmus, 3 had fatigue, 3 had hypotonia, 2 had vomiting and 1 had irritability. Thyroglobulin antibody (TgAb) was 500.0 (298.9,587.2) kU/L and thyroid peroxidase antibody (TPOAb) was 621.9 (449.6,869.4) kU/L in 13 cases. Autoantibodies were positive in 9 cases, and cerebrospinal fluid leukocytosis was seen in 4 cases. Regarding electroencephalography result, 4 cases had background slowing and 1 case had occasional sharp waves. Among the 3 patients who had relapses, 1 had cerebellar atrophy shown on cranial magnetic resonance imaging (MRI) during the recurrence. All the patients received intravenous immunoglobulin (IVIG) and intensive methylprednisolone therapy during the first onset, followed by the disappearance of the symptoms, 1 patient had repeated episodes which was decreased after immunosuppressive treatment with Rituximab.Followed up for 25.0 (22.5,33.3) months after the last episode, 12 achieved complete remission and 1 had a wide base gait. Conclusions: Trunk ataxia is the common symptom of Hashimoto's encephalopathy presenting with isolated cerebellar ataxia in children.Children with cerebellar ataxia should be tested for TgAb and TPOAb to detect Hashimoto's encephalopathy, avoiding missed diagnosis and treatment delays; IVIG and intensive steroid therapy is effective, and immunosuppressive therapy for patients with multiple relapses could reduce the recurrence.

Abstract
Objective: To study the effect of hepatitis B virus X protein (HBx) expression level on migration and invasion of zonula occludens protein-1 (ZO-1) in HepG2 liver cancer cells. Methods: Liver cancer cells were transfected with HBV full gene plasmid (pcDNA3.1-HBV1. 1 or pcDNA3.1-HBV1.3), empty plasmid (pcDNA3.1) and HBV-encoded protein plasmids (pHBc, pHBs, pHBp and pHBx), respectively. Western blot and RT-PCR were used to detect ZO1 protein and mRNA levels. Immunoprecipitation was used to detect transfected pHBx. Western blot was used to detect ZO1 ubiquitination levels. Transwell chambers were used to assess cell migration and invasion. Cell proliferation and lactate dehydrogenase assay was used to detect siRNA transfecting targeting ZO1. Flow cytometry was used to detect cell apoptosis and cycle. The data was compared between two and multiple groups by using an independent sample t-test and one-way analysis of variance. Results: Compared with the empty plasmid, ZO1 protein level in HepG2 cells after transiently transfected with pHBV1.1 and pHBV1.3 was decreased by 42.99% ± 6.8% and 55.0% 5 ± 4.56%, respectively, and their mRNA levels did not change significantly. ZO1 protein level in Huh7 cells was decreased by 17.46% ± 4.94% and 47.53% ± 3.38%, respectively. ZO1 protein level after transfection with pHBx was decreased by 47.02% ± 3.4%, while the ZO1 protein level after transfection with pHBc, pHBs and pHBp did not change significantly. ZO1 mRNA level was unaffected with pHBx transfection. ZO1 ubiquitin level and cell migration and invasion ability in HepG2 cells was significantly increased with transfected pHBx. HepG2 cells proliferation, apoptosis and cycle after transfection with ZO1-targeted siRNA did not change significantly, but the migration and invasion ability were significantly increased. Conclusion: HBx can increase the migration and invasion of liver cancer cells by promoting the ubiquitination and degradation of ZO1 protein level.

Abstract
Background: The genetic susceptibility to ischemic stroke (IS) is still not well-understood. Recent genome-wide association studies (GWASes) found that several single nucleotide polymorphisms (SNPs) in the Diacylglycerol acyltransferase 2 gene (DGAT2) and monoacylglycerol O-acyltransferase 2 (MOGAT2) cluster were associated with serum lipid levels. However, the association between the DGAT2-MOGAT2 SNPs and serum lipid phenotypes has not yet been verified in the Chinese people. Therefore, the present study was to determine the DGAT2-MOGAT2 SNPs and gene-environment interactions on serum lipid profiles and the risk of IS. Methods: Genotyping of 5 SNPs (DGAT2 rs11236530, DGAT2 rs3060, MOGAT2 rs600626, MOGAT2 rs609379, and MOGAT2 rs10899104) in 544 IS patients and 561 healthy controls was performed by the next-generation sequencing technologies. The association between genotypes and serum lipid data was determined by analysis of covariance, and a corrected P-value was adopted after Bonferroni correction. Unconditional logistic regression analysis was performed to assess the association between genotypes and the risk of IS after adjustment of potential confounders. Results: The rs11236530A allele was associated with increased risk of IS (CA/AA vs. CC, OR = 1.45, 95%CI = 1.12-1.88, P = 0.0044), whereas the rs600626G-rs609379A-rs10899104G haplotype was associated with decreased risk of IS (adjusted OR = 0.67, 95% CI = 0.48-0.93, P = 0.018). The rs11236530A allele carriers had lower high-density lipoprotein cholesterol (HDL-C) concentrations than the rs11236530A allele non-carriers (P < 0.001). The interactions of rs11236530-smoking, rs3060-smoking and rs10899104-smoking influenced serum apolipoprotein B levels, whereas the interactions of rs11236530- and rs3060-alcohol affected serum HDL-C levels (P I < 0.004-0.001). The interaction of rs600626G-rs609379A-rs10899104G-alcohol (OR = 0.41, 95% CI = 0.22-0.76) and rs600626G-rs609379C-rs10899104T-alcohol (OR = 0.12, 95% CI = 0.04-0.36) decreased the risk of IS (P I < 0.0001). Conclusions: The rs11236530A allele was associated with decreased serum HDL-C levels in controls and increased risk of IS in patient group. The rs600626G-rs609379A-rs10899104G haplotype, the rs600626G-rs 609379A-rs10899104G-alcohol and rs600626G-rs609379C-rs10899104T-alcohol interactions were associated with decreased risk of IS. The rs11236530 SNP may be a genetic marker for IS in our study populations.

Abstract
Background: The current study aimed to investigate the effects of synaptotagmin-like 3 (SYTL3) and solute carrier family 22 member 3 (SLC22A3) single nucleotide polymorphisms (SNPs) and gene-environment (G × E) interactions on blood lipid levels as well as the risk of coronary artery disease (CAD) and ischaemic stroke (IS) in the Southern Chinese Han population. Methods: The genetic makeup of 6 SYTL3-SLC22A3 SNPs in 2269 unrelated participants (controls, 755; CAD, 758 and IS, 756) of Chinese Han ethnicity was detected by the next-generation sequencing techniques. Results: The allele and genotype frequencies of the SYTL3 rs2129209 and SLC22A3 rs539298 SNPs were significantly different between the case and control groups. The SLC22A3 rs539298 SNP was correlated with total cholesterol (TC) levels in controls, the rs539298G allele carriers maintained lower TC levels than the rs539298G allele non-carriers. At the same time, the SLC22A3 rs539298 SNP interacted with alcohol consumption reduced the risk of CAD and IS. The SYTL3-SLC22A3 A-C-A-A-A-A, G-T-C-G-C-A and A-T-A-A-C-A haplotypes increased and the A-C-A-A-C-G haplotype reduced the risk of CAD, whereas the SYTL3-SLC22A3 A-C-A-A-A-A, G-T-C-G-A-G and A-T-A-A-C-A haplotypes increased and the A-C-A-A-A-G and A-C-A-A-C-G haplotypes reduced the risk of IS. In addition, several SNPs interacted with alcohol consumption, body mass index ≥ 24 kg/m2 and cigarette smoking to affect serum lipid parameters such as triglyceride, high-density lipoprotein cholesterol, TC, and apolipoprotein A1 levels. Conclusions: Several SYTL3-SLC22A3 variants, especially the rs539298 SNP, several haplotypes, and G × E interactions, were related to blood lipid parameters and the risk of CAD and IS in the Southern Chinese Han population.

Abstract
Objective: To investigate the association between trimethylamine-N-oxide (TMAO) and the degree of coronary atherosclerosis in coronary heart diseases (CHD) patients with type 2 diabetes mellitus. Methods: Consecutive patients, who underwent coronary angiography due to suspected CHD in Beijing Hospital from November 2016 to January 2018, were screened in this cross-sectional study. According to blood glucose level, previous medical history and coronary angiography results, they were divided into CHD without type2 diabetes mellitus(CHD-nDM) group and CHD with type2 diabetes mellitus(CHD-DM) group. Plasma TMAO levels in each group were measured by LC-MS/MS. Spearman correlation analysis was used to evaluate the correlation between TMAO and the number of diseased vessels and Gensini scores. Multivariate logistic regression was used to analyze the correlation between TMAO and high Gensini scores. Results: A total of 590 patients were enrolled in the study, including 238 patients in CHD-DM group and 352 patients in CHD-nDM group. Patients were older, body mass index, blood pressure level, prevalence of history of hypertension and statins use were higher in CHD-DM group than in CHD-nDM group (all P<0.05). The proportion of patients with multivessel disease (2 or more vessels) was also higher in CHD-DM group than in CHD-nDM group (P<0.001). Gensini score was higher in CHD-DM group than in CHD-nDM group (P<0.05). Fasting blood glucose, glycosylated hemoglobin and urea were significantly higher, while low-density lipoprotein cholesterol and hemoglobin were significantly lower in CHD-DM group than in CHD-nDM group (all P<0.05). The levels of TMAO was significantly higher in CHD-DM group than in CHD-nDM group (P<0.001). Spearman correlation analysis showed that TMAO was positively correlated with the number of diseased vessels, Gensini score, age and blood glucose level (r=0.178, 0.189, 0.260, 0.111, respectively, all P<0.01). Multivariate logistic regression analysis showed that, TMAO level was still positively correlated with high Gensini score in CHD-DM group (OR=2.25, 95%CI 1.16-4.38, P=0.017), but not in CHD-nDM group (OR=1.29, 95%CI 0.72-2.31, P=0.386) after adjusting for age, sex, body mass index, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total cholesterol, triglyceride, history of hypertension, hyperlipidemia, smoking and statin use. Conclusions: In CHD patients with tupe 2 diabetes mellitus, the plasma TMAO level is significantly increased and is independent and positively correlated with the degree of coronary artery disease.

Abstract
AIMS To investigate the effects of three symbiotic Bradyrhizobium strains on peanut growth and on rhizobacterial communities in flowering and harvest stages in an organic farm, also to evaluate the role of plant development in influencing peanut rhizobacterial microbiota and correlations among the inoculants, rhizobacterial communities and plant growth. METHODS AND RESULTS Peanut seeds were inoculated with three individual Bradyrhizobium strains, plant growth performance was measured in two developmental stages and rhizobacterial communities were analysed by Illumina sequencing of rpoB gene amplicons from peanut rhizosphere. The three bradyrhizobial inoculants significantly increased the nodule numbers and aboveground fresh weight of peanut plants regardless of the different growth stages, and the pod yields were increased to some extent and significantly positively correlated with Bradyrhizobium abundances in rhizosphere. Principal coordinate analysis indicated that the rhizobacterial communities were strongly influenced by the inoculation and peanut developmental stages. The bradyrhizobia inoculation increased relative abundances of potentially beneficial bacteria in peanut rhizosphere, and also altered rhizobacterial co-occurrence association networks and important network hub taxa. Similarly, plant development also significantly influenced the structure, composition and co-occurrence association networks of rhizobacterial communities. CONCLUSIONS Bradyrhizobial inoculants increased peanut growth and yields, they and plant development affected the assembly of peanut rhizobacterial communities. SIGNIFICANCE AND IMPACT OF THE STUDY Rhizobial inoculants improved the host plant performance that might also be associated with the dynamic changes in rhizobacterial community except enhancing the biological nitrogen fixation and helps to profoundly understand the mechanism how rhizobia inoculants improve plant growth and yields.

Abstract
The pandemic of COVID-19 in early 2020 is a big challenge to the mechanism of major epidemic prevention and control, the national public health management system, as well as medical and health resources in China. Going through the COVID-19 crisis, we should fully understand the problems and vulnerabilities of the current public health system in China, and it is imperative to deepen and strengthen the public health system which should be throughout whole life cycle and whole process. Oral cavity is the first portal of human body, while illness finds its way in by the mouth. Oral health is highly related to general health and quality of life. The outbreak has drawn the public's attention to the public health system. The establishment and improvement of the oral public health system with the concept of "public health with Chinese characteristics" should also attract people's attentions and thoughts. Furthermore it is urgent to recognize the importance of oral public health.

Abstract
Objective: To investigate the clinical characteristics, treatment and prognosis of myelin oligodendrocyte glycoprotein antibody-associated optic neuritis (MOG-ON) in pediatric patients. Methods: Clinical data, laboratory examination, the initial best corrected visual acuity (BCVA), fundus, neuroelectrophysiological results, MRI imaging, treatment and prognosis of children diagnosed with MOG-ON from 2016 to 2019 were retrospectively analyzed. Results: A total of 29 eyes from 16 children were involved, with a male/female ratio of 1∶1, onset age of (7.0±2.9) years. Seven of 16 patients had prodromal infection, with a unilateral/bilateral ratio of 3∶13, and 2 cases had recurrent optic neuritis. Before treatment, BCVA of 19 eyes (65.5%) was ≤0.1, among them, 4 had no sense of light, 5 had light sense, 5 with sense of hands in front of eyes, and 5 with sense of fingers in front of eyes. There were 10 eyes (34.5%) with BCVA of 0.1-0.5. After treatment, there were 4 eyes (13.8%), 5 eyes (17.2%) and 20 eyes (69.0%) in groups with BCVA of 0.1-0.5, 0.5-1.0, and>1.0, respectively. Twelve of 16 patients had optic papillitis in fundus examination during acute phase. The latency was prolonged and the amplitude was decreased in P100 wave of all the children. Thirteen out of 16 children showed swelling and thickening of optic nerve in MRI T2WI. MRI images exhibited intracranial demyelinating lesions in 12 of 16 children and long segment spinal cord lesions in 3 of 16 children. Thirteen of 16 patients showed effective results after intravenous methylprednisolone (IVMP) and intravenous immunoglobulin (IVIG) treatment. There was no relapse after administration of mycophenolate mofetil in 2 recurrent children. No progression after administration of rituximab was found in 1 child with corticosteroid insensitivity. The average follow-up time was (16±9) months and no recurrence occurred. Ten of 16 patients had full recovery, 4 had significant improvement, and 2 showed no significant improvement. Conclusions: There is no significant gender difference in the incidence of pediatric MOG-ON. Bilateral involvement and severe visual impairment are common in acute phase. Most patients have good response to IVMP combined with IVIG treatment and hence have a good prognosis. Only a few of them have neurological sequelae.

Abstract
The present study was carried out to investigate the changes in amino acid (AA) contents of crop milk and plasma and mRNA abundance of AA transporters and AA synthesis-related enzymes in the crop tissue of male and female pigeons during incubation and chick-rearing periods. Forty-two pairs of adult White King pigeons with 2 fertile eggs per pair were randomly divided into 7 groups by different breeding stages. The AA content of crop milk decreased from day 1 (R1) to day 25 (R25) of chick rearing (P < 0.05). In both male and female adult pigeons, the contents of Thr, Leu, Val, His, Asp, and Pro in plasma increased to maximum levels on R25. Parental sex effect and interaction between stage and sex were observed in the AA contents of pigeon plasma (P < 0.05). For AA transporters, the mRNA abundances of SNAT2, ASCT1, LAT1, and y+LAT2 in the male crops reached the highest value on day 17 of incubation (I17), and the peak mRNA levels of PAT-1, xCT, b0,+AT, and CAT1 were found on R7 (P < 0.05). In females, the abundances of ASCT1, B0AT1, asc-1, and CAT1 mRNA peaked on R1, whereas the maximum levels of LAT1, PAT-1, b0,+AT, and y+LAT2 were observed on R7. For enzymes involved in AA synthesis, the highest gene expressions of glutamate dehydrogenase 1, acetolactate synthase in both parent pigeons, and L-threonine 3-dehydrogenase in female pigeon crops were attained on I17. The expressions of ornithine-δ-aminotransferase, glutamic-oxal(o)acetic transaminase 1, glutamic-oxal(o)acetic transaminase 2, asparagine synthetase, serine hydroxymethyltransferase 2, and glutamic-pyruvic transaminase 2 in both sexes and argininosuccinate lyase and L-threonine 3-dehydrogenase in males were the highest on R1. In conclusion, AA used for pigeon crop milk formation may originate from plasma and intracellular synthesis. The genes involved in AA transport and synthesis varied significantly with sexual effects, indicating that other factors should be considered in future explorations of the mechanism of protein formation in crop milk.

Abstract
Objective: To analyze the clinical features, outcome and prognosis of pediatric myelin oligodendrocyte glycoprotein (MOG) antibody associated acute disseminated encephalomyelitis (ADEM), and provide evidence for improving the diagnosis and treatment of this disease. Methods: This study involved 30 MOG antibody-associated ADEM patients in the Department of Neurology, Guangzhou Women and Children's Medical Center. Patients' clinical information were analyzed. Results: The mean onset age was (5.2±3.3) years old, the ration of male to female was 16∶14. Fifty percent of these patients had a history of precede infection or vaccination before onset. Encephalopathy and seizures were the most common clinical manifestations, followed by movement disorder. In addition, some patients had other positive autoantibodies. Brain Magnetic resonance imaging (MRI) showed extensive, asymmetrical, indefinite large patchy lesions in bilateral cortical and subcortical areas and the spinal cord was characterized by long segmental myelitis. In acute attack, the patients had a good response to corticosteroid combined immunoglobulin therapy. Most of these patients had a good prognosis and recurrence rate was about 20%. Conclusions: The onset age of MOG antibody-associated ADEM is around 5 years old. Encephalopathy and seizures were the most common clinical manifestations. Most patients have a good response to corticosteroid combined immunoglobulin therapy. Some patients may have a recurrent disease course.

Abstract
The X Kell blood group complex subunit-related family member 6
(XKR6) gene single-nucleotide polymorphisms (SNPs) have
been associated with serum lipid profiles and the risk of coronary heart disease
(CHD) and ischemic stroke (IS) in several previous studies, but the association
between the XKR6 rs7014968 SNP and serum lipid levels and the
risk of CHD and IS has not been detected previously. This study aims to explore
the association between the XKR6 rs7014968 SNP and serum lipid
traits and the susceptibility to CHD and IS in the Guangxi Han Chinese
population. Snapshot technology was used to determine the genotypes of the
XKR6 rs7014968 SNP in 624 controls, 588 patients with CHD,
and 544 patients with IS. The XKR6 rs7014968C allele carriers
in the control group had higher serum total cholesterol (TC) levels than the C
allele noncarriers (P = .025). The XKR6
rs7014968C allele carriers also had an increased risk of CHD and IS
(P < .05-.01). Stratified analysis showed that the
patients with the rs7014968C allele in the female, age >60 years, body mass
index (BMI) >24 kg/m2, and hypertension subgroups had a higher
risk of CHD than those in the subgroup counterparts. The patients with the
rs7014968C allele in the male, BMI > 24 kg/m2, smoker, and
hypertension subgroups also had a higher risk of IS than those in the subgroup
counterparts. These results suggest that the XKR6 rs7014968 SNP
is likely to increase the risk of CHD and IS by increasing serum TC levels in
our study populations.

Abstract
Objective: To explore the clinical manifestation and treatment strategy for descending necrotizing mediastinitis (DNM). Methods: A total of 27 cases diagnosed as DNM from January 2010 to August 2018 in the First People's Hospital of Foshan were reviewed. There were 16 males and 11 females, age ranged from 16 to 84 years. The clinical data were collected. SPSS 16.0 software and chi square test were used for statistical analysis. Results: ALL 27 cases were diagnosed as DNM by contrast-enhanced CT scan of the neck and chest. Among the 27 cases, 13 cases resulted from peritonsillar abscess, 8 cases from esophageal foreign body perforation, 5 cases from parapharyngeal and retropharyngeal space abscess, and one case from infection of oral cavity. These 27 cases were divided into three subtypes according to the sites of mediastinitis, including 11 cases for typeⅠ, 5 cases for type ⅡA and 11 cases for type ⅡB. Of 27 cases, 20 cases underwent transcervical drainage for DNM, of which 5 cases with tracheotomy and 6 cases with thoracic drainage, and finally 19 of the 20 patients were cured, and one patient died of bacteremia; 7 cases refused to received surgery and were routinely treated with antibiotics, of which, one case was cured and 6 cases died. The curative rate in patients underwent surgery was significantly higher than that in patients treated with medication (χ(2)=13.638, P<0.001). Among the 20 cured cases, 4 cases were combined with diabetes mellitus and 6 cases with necrotizing fasciitis, while in the 7 died cases, 5 cases were combined with diabetes mellitus and 6 cases with necrotizing fasciitis. The comorbidity rates of diabetes mellitus (χ(2)=4.074, P=0.044) and necrotizing fasciitis (χ(2)=4.457, P=0.035) in died cases were significantly higher than those in cured cases. Conclusion: DNM is a serious infection, with high mortality especially in patients with diabetes and necrotizing fasciitis. Timely cervical and chest enhanced CT scan play vital role in its diagnosis. DNM can be treated effectively with transcervical drainage.

Abstract
Background A new approach for prosthesis-based breast reconstruction is the use of a titanium-coated polypropylene mesh TiLOOP® Bra. However, the safety and outcomes are currently unclear in Chinese breast cancer patients. Methods A retrospective study of patients undergoing prosthesis-based breast reconstruction using TiLOOP® Bra was carried out. Complications were divided into minor complications (require conservative treatment) and major complications (require surgical intervention). The influence of patient- and surgery-related characteristics on complications was analyzed. Results Postoperative hematoma and seroma were respectively found in one and two breasts and could be treated conservatively. In three breasts skin infection occurred immediately after surgery resulting in skin necrosis of two breasts and wound dehiscence of one breast. These three breasts were treated with mesh removal, and revisionary surgery. Increased risk of mesh removal and implant explantation were observed in case of skin infection (P = 0.011) and skin necrosis (P = 0.033). Neither patient-related characteristics including age >50 years, BMI >25 kg/m2, and postoperative radiotherapy/chemotherapy, nor surgery-related characteristics including sentinel lymph node biopsy or axillary dissection alone, and curative/prophylactic surgery were significantly correlated with minor and major complications. Ultrasound evaluation showed a well-incorporated mesh into surrounding tissue. Conclusion This titanium-coated polypropylene mesh showed acceptable complications and could be used safely in prosthesis-based breast reconstruction by stabilizing the implant pocket. Longer follow-up data and more randomized trials are necessary to determine the clinical use of this mesh.

Abstract
Background Long non-coding RNAs (lncRNAs) are involved in numerous physiological functions. Yet, their mechanisms in coronary artery disease (CAD) are not well understood. Methods The expression profile of genes associated to CAD was reannotated into the lncRNA-mRNA biphasic profile. The target microRNA data were used to design a global CAD triple network. Thereafter, we conducted a functional enrichment analysis and clustering using the triple network from the level of topology analyses. The expression of four non-coding RNAs (ncRNAs) was measured by qRT-PCR and the risk of CAD was calculated by nomogram. The prognostic value of three ncRNAs was evaluated using receiver operating characteristic (ROC) curve. Results A CAD lncRNA-miRNA-mRNA network was constructed which included 15 mRNAs, 3 miRNAs, 19 edges and one lncRNA. Nomogram showed that four ncRNAs were the risk of CAD. After RT-PCR validation in four ncRNAs between CAD and non-CAD samples, only three ncRNAs had significant meaning for further analysis. ROC curve showed that TWF1 presented an area under curve (AUC) of 0.862, the AUC of hsa -miR-142-3p was 0.856 and hsa -miR126-5p was 0.822. After the pairwise comparison, we found that TWF1 had significant statistical significance (P TWF1-142 < 0.05 and P TWF1-126 < 0.01). The results of functional enrichment analysis of interacting gene and microRNA showed that the shared lncRNA TWF1 may be a new factor for CAD. Conclusions This investigation on the regulatory networks of lncRNA-miRNA-mRNA in CAD suggests that a novel lncRNA, lncRNA TWF1 is a risk factor for CAD, and expands our understanding into the mechanisms involved in the pathogenesis of CAD.

Abstract
BACKGROUND This study investigated the pathways and genes involved in coronary artery disease (CAD) and the associated mechanisms. METHODS Two array data sets of GSE19339 and GSE56885 were downloaded. The limma package was used to analyze the differentially expressed genes (DEGs) in normal and CAD specimens. Examination of DEGs through Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment and Gene Ontology annotation was achieved by Database for Annotation, Visualization and Integrated Discovery (DAVID). The Cytoscape software facilitated the establishment of the protein-protein interaction (PPI) network and Molecular Complex Detection (MCODE) was performed for the significant modules. RESULTS We identified 413 DEGs (291 up-regulated and 122 down-regulated). Approximately 256 biological processes, only 1 cellular component, and 21 molecular functions were identified by GO analysis and 10 pathways were enriched by KEGG. Moreover, 264 protein pairs and 64 nodes were visualized by the PPI network. After the MCODE analysis, the top 4 high degree genes, including interleukin 1 beta (IL1B, degree = 29), intercellular adhesion molecule 1 (ICAM1, degree = 25), Jun proto-oncogene (JUN, degree = 23) and C-C motif chemokine ligand 2 (CCL2, degree = 20) had been identified to validate in RT-PCR and Cox proportional hazards regression between CAD and normals. CONCLUSIONS The relative expression of IL1B, ICAM1 and CCL2 was higher in CAD than in normal controls (P < 0.05-0.001), but only IL1B and CCL2 genes were confirmed after testing the gene expression in blood and/or analyzing in Cox proportional hazards regression (P < 0.05-0.001), and the proper mechanism may involve in the AGE-RAGE signaling pathway, fluid shear stress, the tumor necrosis factor (TNF) and cytokine-cytokine receptor interaction.

Abstract
This study aimed to assess the association of the tribbles pseudokinase 1 (TRIB1) and transcriptional repressor GATA binding 1 (TRPS1) single nucleotide polymorphisms (SNPs) and the gene-gene (G × G) and gene-environment (G × E) interactions with serum lipid levels, the risk of coronary heart disease (CHD) and ischemic stroke (IS) in the Guangxi Han population. Genotyping of the rs2954029, rs2980880, rs10808546, rs231150, rs2737229 and rs10505248 SNPs was performed in 625 controls and 1146 unrelated patients (CHD, 593 and IS, 553). The genotypic and allelic frequencies of some SNPs were different between controls and patients (CHD, rs2954029 and rs231150; IS, rs2954029 and rs2980880; P < 0.05-0.01). Two SNPs were associated with increased risk of CHD (rs2954029 and rs231150) and IS (rs2954029) in different genetic models. Several SNPs in controls were associated with total cholesterol (rs2954029, rs2980880 and rs2737229), triglyceride (rs2954029 and rs10808546), low-density lipoprotein cholesterol (rs2954029), high-density lipoprotein cholesterol (rs2980880 and rs231150) and apolipoprotein A1 (rs2737229) levels. The rs2954029TA/AA-age (>60 year) interaction increased the risk of CHD, whereas the rs10808546CT/TT-drinking interaction decreased the risk of IS. The rs2954029A-rs2980880C-rs10808546C haplotype was associated with increased risk of CHD and IS. The rs2954029A-rs2980880T-rs10808546C haplotype was associated with increased risk of CHD. The rs2954029-rs231150 interactions had an increased risk of both CHD and IS. These results suggest that several TRIB1 and TRPS1 SNPs were associated with dyslipidemia and increased risk of CHD and IS in our study population. The G × G and G × E interactions on serum lipid levels, and the risk of CHD and IS were also observed.

Abstract
A novel optical antenna for optical phased arrays is proposed and simulated. A high-contrast grating structure is used to achieve extremely efficient emission. The emission efficiency is as high as 93.94% at 1.55 μm, which exceeds 50% in a range of wavelength from 1.48 μm to 1.62 μm. The antenna can achieve a perfect grating lobe suppression with background suppression of 28.4 dB when the phase difference between adjacent waveguides is 0. A 16-wire optical phased array can easily achieve a scan range of ± 22.8° × 20.2° with a beam width of 2.4° × 2.5°, by employing the optical antenna proposed.

Abstract
Little is known about the association of monoacylglycerol acyltransferase 1 gene (MGAT1) rs634501 single nucleotide polymorphism (SNP) and serum lipid profiles in the Chinese populations. The aim of this study was to detect the association of the MGAT1 rs634501 SNP and several environmental factors with serum lipid levels in the Chinese Maonan and Han populations. Genotypes of the SNP in 2014 unrelated participants (Han, 986; Maonan, 1028) were determined by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and confirmed by direct sequencing. The genotypic and allelic frequencies of the MGAT1 rs634501 SNP were significantly different between the Han and Maonan populations as well as between males and females in the Maonan population. The A allele carriers had lower serum apolipoprotein (Apo) A1 levels, the ApoA1/ApoB ratio and higher ApoB levels in Maonans; and lower high-density lipoprotein cholesterol, ApoA1 levels, ApoA1/ApoB ratio, and higher triglyceride levels in Han than the A allele non-carriers. There were also different associations of the MGAT1 rs634501 SNP and serum lipid profiles between males and females in the both ethnic groups. Serum lipid parameters in the two ethnic groups were also associated with several environmental factors. These results suggest that the association of the MGAT1 rs634501 SNP and serum lipid parameters might have ethnic- and/or sex-specificity.

Abstract
Objective: To confirmed the polymorphisms of HLA-DQ and IFNL4 were associated with HBV infection and clearance in a Chinese population. Methods: The Sequenom MassARRAY MALDI-TOF system was used to genotype the HLA-DQrs9275319 and IFNL4rs368234815, rs12971396, rs12979860, and rs8099917. A binary logistic regression test was conducted to estimate the relative risk of these SNPs with HBV infection and clearance. Haploview4.2 software and PHASE software (v2.0.2) were employed to analyze linkage disequilibrium (LD) and haplotype frequencies. The MDR program was applied to analyze interactions between SNP and SNP.Statistical analysis was performed using SPSS 19.0 and P-values were corrected by Bonferroni's corrections. Results: A total of 1,069 subjects were recruited and divided into three groups: 238 healthy controls(HC), 397 with HBV-related chronic liver disease (CLD), 434 with spontaneous clearance (SC). The rs9275319TT was most frequently identified among all groups(86.2% in the CLD group, 77.6% in the SC group, and 75.9% in the HC group).Carriage of the rs9275319 C allele was a protective factor for chronic HBV infection (the allele model: P = 0.000 3, OR,0.514; 95% CI, 0.359-0.738) and clearance (the allele model: P = 0.002, OR, 1.659; 95% CI, 1.197-2.300). HLA-DQ rs9275319 showed a significant association with HBV infection (allele model, OR, 0.514; 95% CI, 0.359-0.738, adjusted P = 0.000 3) and spontaneous clearance (allele model, OR, 1.659; 95% CI, 1.197-2.300, adjusted P = 0.002). However, there was no association between IFNL4 polymorphism and HBV infection((allele model: P = 0.082 for rs368234815; P = 0.063 for rs12971396; P = 0.517 for rs12979860; P =0.695 for rs8099917) or spontaneous clearance ((allele model: P = 0.358 for rs368234815; P = 0.105 for rs12971396; P = 0.640 for rs12979860; P = 0.640 for rs8099917;all P > 0.05). The multifactor dimensionality reduction (MDR) test showed there was a three-way interaction (rs12971396, rs12979860, and rs9275319) between IFNL4 and HLA-DQ polymorphisms for HBV infection (permutation P = 0.009 for the best factor model) and clearance (permutation P = 0.014 for the best factor model). Conclusion: The SNP-SNP interaction between HLA-DQ and IFNL4 is associated with the regulation of HBV infection and natural clearance.

Abstract
Background This study aimed to assess the association between the angiopoietin-like protein 4 gene (ANGPTL4) single nucleotide polymorphisms (SNPs) and serum lipid levels, the risk of coronary artery disease (CAD) and ischemic stroke (IS), and response to atorvastatin therapy in a Southern Chinese Han population. Methods Genotypes of the ANGPTL4 rs4076317, rs7255436, rs1044250 and rs2967605 SNPs in 1,654 unrelated subjects (CAD, 568; IS, 537; and controls, 549) were determined by the Snapshot technology. Another group of 724 hyperlipidemic patients was selected and treated with atorvastatin calcium tablet 20 mg/day for 8 weeks. Results The rs2967605 CT/TT genotypes were associated with a decreased risk of CAD (adjusted OR = 0.68, 95% CI = 0.47-0.99, P = 0.043 for CT/TT vs. CC) and IS (adjusted OR = 0.55, 95% CI = 0.38-0.80, P = 0.020 for CT/TT vs. CC). There was no significant association between the four SNPs and angiographic severity of CAD. The subjects with the rs4076317 CG/CC genotypes in controls had higher total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels than the subjects with the GG genotype (P < 0.001; a P < 0.0018 was regarded statistically significant by the Bonferroni correction). The subjects with rs4076317CG/GG genotypes had lower TC and LDL-C levels than the subjects with CC genotype after atorvastatin treatment (P < 0.001). Conclusions The observed associations suggest that the ANGPTL4 variants have a potential role on serum lipid levels and atherosclerosis-related diseases in the Chinese Han population, especially the ANGPTL4 rs4076317 and rs2967605 SNPs.

Abstract
Previous genome-wide association studies have showed that several tetratricopeptide repeat domain protein 39B gene (TTC39B) single nucleotide polymorphisms (rs581080 and rs471364) were associated with serum high-density lipoprotein cholesterol levels among populations of European ancestry, but the results are inconsistent. Furthermore, little is known about the association between TTC39B SNPs and the susceptibility to coronary heart disease (CHD) and ischemic stroke (IS). Therefore, this study was undertaken to detect the association between the TTC39B rs1407977 SNP and serum lipid levels and the risk of CHD and IS in a Southern Chinese Han population. Genotyping of the SNP in 1741 unrelated subjects (healthy controls, 624; CHD patients, 578 and IS patients, 539) was performed by the Snapshot Technology. The genotypic and allelic frequencies of the SNP were different between the control subjects and CHD patients, or between the control subjects and IS patients (P ≤ 0.001). The T allele frequency was higher in CHD (16.2%) and IS (15.0%) patients than in controls (9.8%). The T allele carriers had higher risk of CHD (OR = 1.728, 95% CI = 1.290-2.316, P < 0.001) and IS (OR = 1.518, 95% CI = 1.182-2.116, P = 0.002) than the T allele non-carriers after controlling for potential confounders. No significant association was observed between the TTC39B rs1407977 SNP and all seven serum lipid traits. These results suggest that the TTC39B rs1407977 SNP is associated with the risk of CHD and IS in our study population and does not depend on serum lipid levels.

Abstract
Adenoid hypertrophy(AH) and otitis media with effusion (OME) are both common diseases in pediatric otorhinolaryngology and are often associated with each other. Children are often diagnosed with otitis media with effusion and adenoid hypertrophy(OME/AH). Adenoids are immune lymphoid tissues of children's upper respiratory tract, and are important barriers against upper respiratory tract infections.During an upper respiratory tract infection,bacteria or viruses repeatedly stimulate immune lymphoid tissue to cause hyperplasia,and pathological hypertrophy is often accompanied by OME and other related symptoms.In recurrent or chronic OME, hyperproliferative adenoids are usually excised indicating that the two diseases may have a certain correlation. Recently,more and more studies have shown that AH plays an important role in the pathogenesis of OME in children. This article elucidates the role of AH in the pathogenesis of childhood OME from adenoid mechanical obstruction,adenoid bacterial and bacterial biofilm, adenoid local immune regulation, and IgE-mediated allergic reaction.

Abstract
Previous genome-wide association studies have shown that the rs10248618 single nucleotide polymorphism (SNP) in the dynein axonemal heavy chain 11 gene (DNAH11) has been associated with serum high-density lipoprotein cholesterol (HDL-C) levels. However, little is known about such association in the Chinese population. The present study was performed to clarify the association between the DNAH11 rs10248618 SNP and serum lipid traits and the risk of coronary artery disease (CAD) and ischemic stroke (IS) in the Guangxi Han population. Genotypes of the DNAH11 rs10248618 SNP in 1,213 unrelated patients (CAD, 600 and IS, 613) and 631 healthy controls were determined by snapshot technology. The genotypic and allelic frequencies of the SNP were significantly different between the CAD/IS patients and the controls (P < 0.01 for all). The CT/TT genotypes and the T allele were associated with an increased risk of CAD and IS (CAD: P < 0.01 for CT/TT vs. CC and T vs. C; IS: P < 0.01 for CT/TT vs. CC and T vs. C). The CT/TT genotypes in the healthy controls, but not in CAD or IS patients, were associated with a decreased serum HDL-C and apolipoprotein (Apo) A1 concentration. These results suggest that the DNAH11 rs10248618 SNP is associated with the risk of CAD and IS in our study population. It is likely to increase the risk of CAD and IS by reducing serum HDL-C and ApoA1 levels.

Abstract
AIMS The aim of the study was to survey rhizobial biogeography and to inoculate soybean with selected rhizobia in China to enhance symbiotic nitrogen fixation (SNF). METHODS AND RESULTS Biogeography, genetic diversity and phylogeny of soybean rhizobia were surveyed. Inocula were prepared and applied to soybean. Results showed that Bradyrhizobium elkanii and Ensifer fredii were widely distributed in acid and alkaline soils respectively. Available iron was detected as the first determinant for distribution of the two rhizobia and the soybean varieties did not greatly affect the rhizobial compatibility. Geographical latitude and precipitation in June were the main geographical and climatic factors affecting the rhizobial distribution. Inoculation with selected rhizobia increased the nodule number, fresh weight, occupation ratio, seed protein content and soybean yields. CONCLUSIONS Selection and application of effective soybean rhizobia across China according to biogeography were clarified to promote the SNF, thereby improving soybean yield. SIGNIFICANCE AND IMPACT OF THE STUDY Rhizobial diversity and biogeography were evaluated systematically in six sites across China. Available iron and soil pH are found to be the most important determinants for the distribution of soybean rhizobia. Inoculation to soybean enhances SNF, positively correlating to the increase in soybean yield and seed protein content.

Abstract
Objective: To classify the morphology of mandible posterior region and provide reference for the planning of dental implantation. Methods: Cone beam CT data of 208 patients were collected. The CT data were imported into CS 3D imaging V3 software and then the morphology of mandible posterior region were analyzed. The types of premolar and molar mandible cross-section morphology were recorded, classified and analyzed. Results: The results showed that type A (vertical type) (79%-96%) was the most common in the premolars, whereas type B (inclined type) (36%-37%) and type C (lingual inverted concave) (30%-54%) were the most common types in the molars, followed type D (absorption severe type) (2%-5%). There was a statistically significant differences in tooth positions (P<0.001), tooth deficiency aspect (P<0.001) and different side (P=0.013), different age (P<0.001), and different gender (P=0.007). Conclusions: Using cone beam CT to determine the morphology of mandible may be a reference for the planning of dental implantation.

Abstract
Background Little is known about the association of the protein phosphatase 1 regulatory subunit 3B gene (PPP1R3B) single nucleotide polymorphisms (SNPs) and serum lipid levels, the risk of coronary artery disease (CAD) and ischemic stroke (IS) in the Chinese populations. This study detected such association in a Southern Chinese Han population. Methods Genotypes of 4 novel PPP1R3B SNPs (rs12785, rs330910, rs330915 and rs9949) in 1704 Han Chinese (CAD, 556; IS, 531 and control, 617) were determined by the Snapshot technology. Results The rs12785A and rs9949A allele frequency was higher in both CAD/IS patients than in controls. The rs330910T and rs330915T allele frequency was also higher in CAD patients than in controls. The rs330910T allele carriers in controls had lower serum low-density lipoprotein cholesterol (LDL-C) levels than the rs330910T allele non-carriers (P < 0.0014). The rs12785A, rs9949A and rs330910T allele carriers were associated with an increased risk of CAD (P = 0.008–0.004). There was strong linkage disequilibrium among the 4 SNPs in the controls and CAD/IS patients. The T-A-A-G haplotype was associated with a decreased risk of CAD and IS, whereas the A-A-T-A haplotype was associated with an increased risk for IS. Haplotype-environment interactions on the risk of CAD and IS were also observed. Conclusions Several PPP1R3B polymorphisms were associated with serum LDL-C levels, the risk of CAD and IS in the Southern Chinese Han population. But these findings still need to be confirmed in the other populations with larger sample sizes.

Abstract
BACKGROUND Little is known about the association of the dedicator of cytokinesis 7 (DOCK7 rs1748195) and angiopoietin like 3 (ANGPTL3 rs12563308) single nucleotide polymorphisms (SNPs) and their haplotypes with serum lipid levels and the risk of coronary artery disease (CAD) and ischemic stroke (IS) in the Chinese populations. This study aimed to detect such association in a Southern Chinese Han population. METHODS This study included 1728 subjects (CAD, 568; IS, 539; and controls, 621). Genotypes of the two SNPs were determined by the Snapshot technology. RESULTS The genotypic and allelic frequencies of the rs1748195 SNP were different between CAD patients and controls (P < 0.05 for each), the rs1748195G allele frequency was higher in CAD patients than in controls (27.6% vs. 23.6%, P = 0.024). The genotypic frequencies of the rs12563308 SNP were also different between CAD patients and controls (P = 0.021). The rs1748195 SNP was associated with an increased risk of CAD after controlling for potential confounders and Bonferroni correction (P < 0.025 considered statistically significant; Recessive: OR = 1.79, 95% CI = 1.04-3.06, P = 0.017; Log-additive: OR = 1.27, 95% CI = 1.02-1.57, P = 0.014), whereas the rs12563308 SNP was associated with a decreased risk of CAD (Dominant: OR = 0.69, 95% CI = 0.45-0.94, P = 0.011; Log-additive: OR = 0.73, 95% CI = 0.49-0.89, P = 0.009). The rs1748195 SNP was also associated with an increased risk of severity to coronary artery atherosclerosis (Dominant: OR = 1.45, 95% CI = 1.07-2.11, P = 0.017; Log-additive: OR = 1.35, 95% CI = 1.09-1.82, P = 0.013). The interactions of SNP-environment on serum lipid levels and the risk of severity to coronary artery atherosclerosis, CAD and IS were noted. The rs1748195G-rs12563308T haplotype was associated with an increased angiographic severity to coronary artery atherosclerosis (OR = 1.46, 95% CI = 1.05-2.03), and the risk of CAD (OR = 1.37, 95% CI = 1.08-1.74). The interactions of haplotype-hypertension on the risk of CAD and haplotype-drinking on the risk of CAD/IS were observed. CONCLUSIONS These results suggest that the DOCK-ANGPTL3 SNPs and their haplotypes were associated with the angiographic severity to coronary artery atherosclerosis and the risk of CAD and IS in the Southern Chinese Han population.

Abstract
BACKGROUND Hepatocyte nuclear factor-1α gene (HNF1A) single nucleotide polymorphisms (SNPs) have been associated with serum lipid traits in several previous genome-wide association studies. However, little is known about such associations in the Chinese populations. The present study aimed to determine the association of the HNF1A rs1169288, rs2259820, rs2464196 and rs2650000 SNPs and serum lipid traits, the risk of coronary artery disease (CAD) and ischemic stroke (IS). METHODS The genotypes of the four SNPs in 562 CAD and 521 IS patients, as well as 594 healthy controls, were detected using the Snapshot technology. RESULTS The genotype and allele distribution of the four SNPs was not different between controls and CAD or IS patients (p > 0.05 for all). rs1169288, rs2259820 and rs2464196 SNPs were significantly associated with serum lipid levels in both controls and CAD patients (p < 0.004-0.009). rs2259820 and rs2464196 SNPs were significantly associated with a lower risk of CAD [odds ratio (OR) = 0.64, 95% confidence interval (CI) = 0.44-0.91, p = 0.015 and OR =0.62, 95% CI = 0.43-0.89, p = 0.010, respectively]. Significant linkage disequilibrium was noted among the four SNPs (r2 > 0.5, D' > 0.8). The haplotype of rs1169288A-rs2259820C-rs2464196G-rs2650000A was associated with an increased risk of CAD (OR =1.95, 95% CI: 1.13-3.37, p = 0.015). Interactions of SNP-SNP (rs1169288-rs2464196-rs2650000) and haplotype-environment on the risk of CAD (A-C-G-A-smoking) or IS (A-C-G-A-sex and A-T-A-C-alcohol consumption) were also observed among these SNPs. CONCLUSIONS These findings suggest that the HNF1A polymorphisms may be the genetic risk factors for CAD and IS.

Abstract
BACKGROUND AND AIMS Obesity is a major worldwide health problem and is often associated with many metabolic diseases. Levels of several serum-specific metabolites may be altered in patients with these metabolic diseases. We aimed to investigate the associations of serum metabolite levels with obesity and traditional risk factors for metabolic disease in Chinese individuals. METHODS AND RESULTS Six-hundred Chinese individuals undergoing annual physical exams were recruited and categorized into overweight/obese and control groups (1:1 ratio). We simultaneously quantified the serum lysophosphatidylcholine (LPC), branched-chain amino acids (BCAA), aromatic amino acids (AAA), 25-hydroxyvitamin D, glutamine (Gln), glutamic acid (Glu), and Gln/Glu ratio levels using our previously established targeted serum metabolomic method. The overweight/obesity group had significantly higher levels of BCAA, AAA, and Glu, as well as lower levels of unsaturated LPC, Gln, and Gln/Glu, than the control group. Correlation analyses revealed significant and positive relationships of saturated LPC, BCAA, AAA, and Glu with blood pressure, glucose, triglycerides, apolipoprotein B, and high-sensitivity C-reactive protein, while unsaturated LPC, Gln, Gln/Glu, and 25-hydroxyvitamin D exhibited an opposite trend. In the multifactor logistic regression model, low unsaturated LPC and Gln/Glu, as well as high BCAA and AAA levels, were found to be independent risk factors for obesity; the odds ratios (95% confidence interval) of the highest quartile compared to the lowest quartile were 0.241 (0.139-0.417), 0.436 (0.252-0.755), 3.944 (2.094-7.430), and 2.357 (1.274-4.361) (P < 0.01), respectively. CONCLUSION LPC, BCAA, AAA, and Gln/Glu are significantly related to obesity development and risk factors of some metabolic diseases.

Abstract
OBJECTIVE To explore the effect of high glucose-based peritoneal dialysis fluids on NLRP3-IL-1β in human peritoneal mesothelial cells. METHODS HMrSV5 cells (SV40 immortalized human peritoneal mesothelial cell line) were grown in type I collagen-coated dishes in DMEM/F12 containing 10% fetal calf serum (FCS). All experiments on HMrSV5 cells were performed between passages 5 and 10. The cells were divided into 7 groups: control, 1.5% dextrose, 2.5% dextrose, 4.25% dextrose, rotenone, thenoyltrifluoroacetone (TTFA), and antimycin A. Immunoblotting was used to evaluate the expression of IL-1β. Small interfering RNA (siRNA) targeting NLRP3 was used to downregulate the expression of NLRP3 and Western blot was used to evaluate the expression of IL-1β in human peritoneal mesothelial cells exposed to 4.25% dextrose. In the meanwhile, resveratrol (RSV) was used to induce autophagy, 3-methyladenine (3-MA) and siRNA against Beclin 1 or ATG5 were used to block auto-phagy, flow cytometric was used to analyze the respiring (mitotracker deep red), total (mitotracker green) and reactive oxygen species (ROS)-generating mitochondria (mitoSOX); Western blot was used to evaluate the expression of IL-1β. RESULTS The IL-1β relative expressions were 0, 0.175±0.082, 0.418±0.163, 2.357±0.288, 2.642±0.358, 3.271±0.462, and 0.123±0.091, indicating that the cells exposed to high glucose-based peritoneal dialysis fluids and cells treated with mitochondria respiratory chain key enzyme complex I, and complex III inhibitors increased the IL-1β expression. And we found that NLRP3 knock-down significantly blocked the upregulation of IL-1β. In addition, the fluorescence intensity of total mitochondria and ROS-generating mitochondria in the following groups: control, negative control, RSV, 3-MA, ATG5 siRNA, Beclin1 siRNA were 1.76±0.42, 1.83±0.55, 1.85±0.62, 7.36±0.92, 5.35±0.77, 5.06±0.62 and 821.68±95.12, 868.15±102.82, 723.39±92.56, 1 660.08±113.65, 1 433.01±107.24, 1 562.36±112.88 respectively. The increased concentrations of mitochondrial ROS and IL-1β upregulation were confirmed in the inhibition but not the induction of auto-phagy. We also found that downregulation of ATG5 and Beclin1 sensitized cells for the release of IL-1β induced by MSU (monosodium urate) or nigericin which was the NLRP3 inflammasome activator. RSV treatment attentuated this effect. CONCLUSION Long-term application of high glucose-based peritoneal dialysis fluids can trigger the consistent activation of NLRP3-IL-1β in peritoneal mesothelial cells. Timely initiation of autophagy may block the NLRP3-IL-1β activation and provide a basis for the further development of a potential therapeutic strategy for delay of chronic inflammation and peritoneal fibrosis associated with peritoneal dialysis.

Abstract
Objective: Characterization and evaluation of the uncertainty of the reference materials of cholesterol in aqueous solution. Methods: The certified reference material GBW09203b was weighed accurately and dissolved into methyl cyclodextrin aqueous solution to prepare six kinds of candidate reference materials of cholesterol according to the concentration. The materials were tested for homogeneity and stability using routine methods and were evaluated the uncertainty derived from the inhomogeneity and instability. The uncertainty due to measurement was derived from the purity of the raw material, the weighing and the density measurement. The certified values and expanded uncertainties were calculated according to the ISO Guide. The expanded uncertainty of the certified value was the combination of standard uncertainty of measurement, inhomogeneity and instability. The coverage factor, k, was determined from the Student's t-distribution corresponding to the calculated effective degrees of freedom and 95% level of confidence. Results: It showed that the six candidate reference materials were homogeneous and were tested to be stable for at least 1 year at -70 ℃ and -20 ℃ using the isochronous stability study. The relative uncertainties due to the inhomogeneity were 0.14%, 0.11%, 0.13%, 0.47%, 0.39% and 0.11%. The relative uncertainty due to the instability was 0.25% at -70 ℃. The uncertainties of measurement were 0.06%, 0.05%, 0.05%, 0.05%, 0.05% and 0.05%.The certified values (reference value ± expanded uncertainty, mmol/L) were as follows: (0.651±0.004), (1.310 ±0.007), (2.574±0.015), (5.210±0.055), (7.710±0.072), (10.242±0.056) mmol/L. Conclusions: Six kinds of certified reference materials for cholesterol in aqueous solution have been prepared, which were homogeneity, stable and reliable. It showed that the uncertainty of measurement was very small compared with the uncertainty due to inhomogeneity and instability.

Abstract
The tetratricopeptide repeat domain protein 39B gene (TTC39B) single nucleotide polymorphism (SNP) of rs581080 has been associated with serum high-density lipoprotein cholesterol (HDL-C) levels. However, little is known about such association in the Chinese populations. The present study was performed to assess the association between the TTC39B rs581080 SNP and serum lipid levels and the risk of coronary artery disease (CAD) and ischemic stroke (IS) in the Guangxi Han population. Genotypes of the TTC39B rs581080 SNP in 1741 unrelated subjects (CAD, 578; IS, 537; and healthy controls; 624) were determined by the Snapshot Technology. The genotypic and allelic frequencies of the TTC39B rs581080 SNP were different between the CAD/IS patients and controls (P < 0.01 for all). The CG/GG genotypes and G allele were associated with an increased risk of CAD (P = 0.001 for CG/GG vs. CC, P = 0.003 for G vs. C) and IS (P = 0.002 for CG/GG vs. CC; P = 0.004 for G vs. C). The CG/GG genotypes in the healthy controls, but not in CAD or IS patients, were also associated with a decreased serum HDL-C concentration. These results suggest that the TTC39B rs581080 SNP is associated with the risk of CAD and IS in our study population. It is likely to increase the risk of CAD and IS by reducing serum HDL-C levels.

Abstract
Previous genome-wide association studies have showed that the rs12670798 variant in the dynein axonemal heavy chain 11 gene (DNAH11) is associated with some serum lipid phenotypes. The present study was undertaken to detect the DNAH11 rs12670798 variant and G × E interactions on serum lipid levels, coronary heart disease (CHD), ischemic stroke (IS), and the lipid-lowering efficacy of atorvastatin in the Chinese Han population. This study included 1,108 unrelated patients (CHD, 568 and IS, 540) and 541 healthy controls. Genotypes of the DNAH11 rs12670798 were determined by the Snapshot technology. A total of 724 hyperlipidemic patients were treated with atorvastatin calcium tablet 20 mg per day for 8 weeks after genotyping. Serum total cholesterol (TC) levels in controls were different among the three genotypes of the rs12670798 (P = 0.019), the C allele carriers had higher TC levels than the C allele non-carriers. The C allele carriers were associated with an increased risk of CHD (CT genotype: OR = 1.345, 95% CI = 0.975-1.855, P = 0.071; CC genotype: OR = 1.590, 95% CI = 1.109-2.278, P = 0.012). The C allele carriers were also associated with an increased risk of IS (CT genotype: OR = 1.597, 95% CI = 1.153-2.213, P = 0.005; CC genotype: OR = 1.722, 95% CI = 1.192-2.488, P = 0.004). The C allele carriers had lower TC, low-density lipoprotein cholesterol, apolipoprotein (Apo) A1 and ApoB levels than the C allele non-carriers after atorvastatin treatment. Stratified analysis showed that the DNAH11 rs12670798 may interact with the gender, age, body mass index, cigarette smoking, and alcohol consumption to affect the risk of CHD and IS. The DNAH11 rs12670798 variant was associated with elevated serum TC levels, and increased risk of CHD and IS in the Chinese Han population. The C allele carriers had higher serum TC levels and the risk of CHD and IS than the C allele non-carriers, but they had lower TC, LDL-C, ApoA1 and ApoB levels than the C allele non-carriers after atorvastatin treatment.

Abstract
BACKGROUND The present study was to detect the association of single nucleotide polymorphism (SNP) in the breast susceptibility gene 2 (BRCA2) and the risk of coronary artery disease (CAD) and ischemic stroke (IS). METHODS Genotypes of the BRCA2 rs9534275 in 1822 unrelated subjects (CAD, 606; IS, 569; and healthy controls, 647) were determined by the polymerase chain reaction and restriction fragment length polymorphism and then confirmed by direct sequencing. RESULTS The genotypic and allelic frequencies of rs9534275 were significantly different between the CAD, IS patients and controls (P = 0.033 and P = 0.027; respectively). The GG, GT/GG genotypes and G allele were associated with an increased risk of CAD and IS (CAD: P = 0.005 for GG vs. TT, P = 0.004 for GT/GG vs. TT, P = 0.005 for G vs. T; IS: P = 0.003 for GG vs. TT, P = 0.005 for GT/GG vs. TT; P = 0.002 for G vs. T). The GG, GT and GT/GG genotypes in the CAD, but not in healthy controls and IS patients, were associated with an increased serum total cholesterol (TC) and apolipoprotein B (ApoB) concentration. CONCLUSIONS The present study shows that the G allele carriers of BRCA2 rs9534275 were associated with increased serum TC and ApoB levels in the CAD patients and increased risk of CAD and IS.
